Good auto top offs for a nano?

[fishnchip]

Hey guys,

I have a 32 gallon biocube and recently made it an open top tank. The water evaporates crazy fast so I'll need to invest in an auto top off system fairly quickly. Just wanted to know what auto top offs you guys use, and if you'd recommend them for my cube.

Thanks, #reefsquad!!

(p.s I'm not trying to spend crazy money on this ato lol)

I use a tunze nano in my biocube 32 and it works just fine

I'll be sure to look into it! Thank you!

For a little more, the regular Tunze, 3155 has redundancy with both an optical sensor and a float switch.

+1 for this :)

Just checked, it is actually about twice the price. I got mine cheap because of Black Friday sales.

Renee,
In the last few years all kinds of Nano ATO's have hit the market, but I'm an ole Tunze guy myself.
Got an old Tunze 3155 and it never missed a beat. Then, Tunze released the Nano.

Tunze Nano in my Red Sea Max C-130. Works great. My ato container is a dog food container from Target.

Pacific Sun Sentry or a Auto Aqua

Same setup. Biocube 32 with a tunze 3155 works amazing. Only complaint is it dumps a cup in on power up which is annoying. But not an issue. I just put a cup under intake hose when needed. I power off when doing water changes

I have 3 Tunze's (two 3152's on cycled QT's and a 3155 on my DT). I have never had them fail me. The one in my DT is 5 years old and the only thing that has every gone wrong is precipitation on the optic sensor from having my dosing pumps emptying too close to it. Fortunately the way it works that makes it think the tank is full and it doesn't add any water.

Smart ATO micro... I tried a bunch of different ones. This will be my standard moving forward

Tunze nano is a great ATO and how could you argue redundancy? ;) However, if it's out of your price range and you are frequently by your tank(as I am), the AutoAqua smart ATO micro is what I use and has been great so far. I also used the Hydor ATO in the past but failed at 6 months. Failure rate for the Hydor seems high from what i've read.

Thanks you guys for all the input! The tunze seems to be pretty popular and efficient so that’s probably be what I’ll go with!
I really appreciate the quick feedback and solid answers. Thank you!!!

This is what I have and works great on my biocube 29... best piece of equipment I’ve ever bought. [emoji1360]

Auto Aqua Smart ATO micro. Been running one on my AIO nano for almost a year with no issues.

I've used Smart ATO. They are good for the price. 2 yrs so far ........ everything is working fine.

I have the Tunze 3155 full size because of the multiple fail safes. I have an IM Fusion 20. It works great and is said to last past the magic 1 year mark.

I'm very happy with my AutoAqua Smart ATO micro.

Why are the auto reservoirs so expensive? Aren't they just contains to hold watero_O
